Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31604894, here are decompositions:

31 + 31604863 = 31604894
127 + 31604767 = 31604894
151 + 31604743 = 31604894
163 + 31604731 = 31604894
283 + 31604611 = 31604894
337 + 31604557 = 31604894
397 + 31604497 = 31604894
523 + 31604371 = 31604894

Showing the first eight; more decompositions exist.
